Gypsum is calcium sulfate di-hydrate, with the chemicalformula CaSO4.2H2O. It is found in several crystallineformations in the Earth crust. It is extracted from the groundand used.

The color of Gypsum naturally is white. It may be seenin the colors of gray, blue, pink, or yellow due to impuritiesin the form of organic materials in clay or ironoxide.

Gypsum has a monoclinic crystallization system with a specificgravity of 2.2 and a hardness of 2. Gypsum mineral iscrystallized in the form of fine and coarse grains; it issoluble in HCl acid and hot water. Pure gypsum contains 20.9%hydrated water and 6.46% SO

Gypsum purity is defined based on the percentage of gypsummineral in it. According to the standards of American Societyfor Testing and Materials (ASTM), at least the purity requiredfor gypsum in industrial materials is 70% of gypsum mineral,with most commercial gypsums having 75 to 99% purity. Theimpurities in gypsum are mostly shale, clays, calciumcarbonates, and sometimes some organic materials.
